I stop by a shop here in WY to barrow a 14 Walker reamer, while I was there the owner picked up a barrel and handed it to me. It looked like a joke, there was this little tiny hole in the end, 12 caliber, after I said a few choice words about it, he said "oh that's the big one" then handed me another barrel.....10 caliber. I guess the plan is to neck down a 17 Hornady Hornet. Should be a real bug killer.
